The Mercy Housing project contains 136 units of one, two and three bedroom apartments. Ninety-two of them will be affordable to those earning 50 percent of San Francisco’s Area Median Income (AMI for the city is currently $96,800 for a family of four, according to city officials.) The other 44 units will go to formerly homeless families making between 15 and 25 percent of AMI.

The complex also includes a 5,400 square foot youth and family center, a primary health clinic and space on the ground floor for shops.

“This is spectacular – a true campus, not just a housing site,” Mayor Gavin Newsom told a crowd huddled outside under heat lamps.

He added that affordable family housing is in great demand in San Francisco, “and we haven’t been fulfilling that need as well as we should have.”
